The **Minimal MPESA Client Library** is a lightweight SDK designed to simplify interactions with MPESA services. It provides an intuitive interface for developers to integrate MPESA functionality, such as authentication and payment processing, into their applications. #### Getting Started To initialize the MPESA client first get the library then use the following code snippet: ```bash go get github.com ``` ```go mpesaClient := mpesa.New( mpesa.Sandbox, // Environment: mpesa.Sandbox or mpesa.Prod nil, // HTTP client: nil for default or provide your custom client consumerKey, // Consumer Key from the MPESA Developer Portal consumerSecret, // Consumer Secret from the MPESA Developer Portal ) ``` - **Environment**: Choose between `mpesa.Sandbox` for development or `mpesa.Production` for live transactions. - **HTTP Client**: Use `nil` to rely on the default HTTP client or supply your own custom configuration. - **Consumer Key & Secret**: Obtain these credentials from the MPESA Developer Portal. #### Authentication Example To retrieve an access token, use the following code: ```go result, respErr, err := mpesaClient.Auth.GetAccessToken() log.Print(result.AccessToken) ``` This snippet authenticates with the MPESA API and logs the generated access token. --- ### Making an STK Push Request The library also simplifies initiating an STK Push (Lipa na M-Pesa Online Payment). Here's an example: ```go res, err := mpesaClient.STKPush.SendRequest(stkpush.Request{ BusinessShortCode: "4646", TransactionType: "CustomerPayBillOnline", Amount: 20, PartyA: "251700404709", PartyB: "4646", PhoneNumber: "251700404709", AccountReference: "Partner Unique ID", TransactionDesc: "Payment Reason", ReferenceData: []stkpush.ReferenceData{ { Key: "ThirdPartyReference", …
